"We used to quip that "password" is the most common password. Now it's "password1." Who said users haven't learned anything about security?"

Als relativ sicher gelten Passwörter aus mindestens 10 Zeichen, willkürlich zusammengesetzt aus Groß-, Kleinbuchstaben, Ziffern und Sonderzeichen. Willkürlich soll heissen, dass die Zeichenkombinationen in keinen Lexikas bzw. Wörterbüchern vorkommen sollten.

Myth: Passwords Must Be Complex to Be Strong.
This is an interesting myth, and we bet you’re thinking we’ve lost it at this point. Of course passwords need to be complex to be strong. No, they do not! They need to be looooonnnngggg. In fact, really, really, long passwords, by their very nature, are often much stronger than a short but complex password.
[...]
Now consider this password:
SeandialVickyandhorusbloomkendallWyoming. It is not complex by any measure. It contains only two character types and all of the components are words. They are, in fact, words picked from the Microsoft password strength checker’s dictionary, which includes 2,254 words. There are 40 characters in this password. The character set those characters are chosen from consist of uppercase and lowercase English characters, or 52 characters in total. That means there are a total of 4.45×1068 1 to 40-character passwords possible from that character set. If you use a brute force attack and you can guess 600 passwords per second, it will take you 1.63×1058 years to guess this password. But you may have captured a connection to a server and have the challenge-response sequence to crack it. In this case it will take you only 1.30×1054 years, assuming you are a nation-state and have access to nearly unlimited computing power.
Oh, but you may argue that these are all words, so we just try combinations of words. Fair enough. Let’s say you even know that it is picked from the password checker dictionary and that you know there are eight words in the password. That improves your ability to crack it significantly. It will now only take 1,948,790,798,336 years to crack.
If we remember correctly from physics class, the universe is about 5,000,000,000 years old, so that means it will take you 390 times longer than the existence of the universe to crack this password, assuming you don’t have to restart your computer to apply a service pack before then.
